RAILWAY TERMINAL STATION.

Specification of Letters Patent.

Patented May 3, 1921.

T 0 @ZZ whom t may concern Be it known that I, JOHN J. CoUGHLrN,

a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin Railway Terminal Stations, of which the following is a specification.

My invention relates to railway terminal stations generally andespecially to stations in metropolitan or congested cities where it isdesirable to have a large number of tracks with adjacent platformsarranged close together and under one roof, and the objects of myimprovements are, first, to economize in space; second, to so arrangethe train tracks with their platforms in such manner that all the trainsare equally accessible from the main public waiting room and ticketofiices; third, to arrange train tracks on the ground level, below theground level and above the ground level; fourth, to so arrange thenecessary incoming switch tracks that an incoming train can be switchedto enter any desirable track in the station be it on the highest levelor the lowest level; fifth, to make a simple, cheap and practicalconstruction and other features to become apparent from the descriptionto follow.

Considerable difficulty has been encountered in an attempt to provide arailway terminal station to accommodate the great number of trainsarriving and departing from metropolitan centers; generally the trackshave been arranged on one level which required a very large area ofsurface and necessitated the patrons to travel a long distance to reachthe remote tracks from the main waiting room and ticket office; thestation tracks required such a large areay that it became a financialburden to purchase the necessary property, furthermore thc complicatednetwork of necessary switches all on the same level caused a delay inthe moving of trains. All these objectionable features are eliminated bythe use of my invention, which to describe so that others versed in theart to which it pertains can make and use the same, I have illustratedon the accompanying two sheets of drawings forming a part of vthisspecification and in which- Figure 1, is a front elevation of a rail-ltrain tracks and switches as they appear on the level above the groundlevel; Fig. 6, is

- a plan View of the converging train tracks and switches as they appearon the ground level partly broken away; Fig. 7, is a diagrammatic viewshowing the tracks on the three levels in side elevation partly brokenaway and Fig. 8, is a cross sectional view taken on line A-A of Fig. 6.Y

Similar reference characters refer to similar parts throughout theseveral views.

The front end of the station buildinor is shown as containing the usualwaiting room 9, with floors 10 above for offices, etc. The train shed 11extends back from the main building and contains the tracks 12 andplatforms 13 on the ground door, the tracks 14 and platforms 15 on theHoor above the ground floor and the tracks 16 and platforms 17 on thefloor below the ground floor. For convenience I have shown twelve traintracks on each of the three floors or levels and it will be understoodthat the number of tracks arranged on each floor may be as many asdesired to accommodate the traffic. The tracks 12 on the ground floor,as seen in Fig. 6,7converge into the four tracks 18; the tracks 14 onthe level below the ground floor converge into the four tracks 19 asseen in Figs. 5 and 6, and the tracks 16 on the level below the groundfloor converge into the four tracks 20 as seen in Fig. 6. The convergingplan of the tracks on said level is preferably identical with the planof the tracks 14 shown in Fig. 5, but of course the tracks 2O must belocated to one side of thetracks 19 outside the train shed to be on thesame level therewith. As viewed in the right hand half of Fig. 6, thetracks 18, 19 and 2O are on the same level, and as clearly shown in thesaid Fig. 6 the tracks 19 and 2O finally converge into tracks 18, at 21where I have shown four tracks as composing the main line entering thestation. The number of tracks composing the main line entering thestation may be as many as desired.

Having thus fully described my invention as shown and described.

what l claiin as new and desire to secure by Letters Patent of theUnited States is :n

l. ln a railway terniinal station, a plu` rality of tracks arranged inthree groups, one in advance of the other, the tracks oi the outer groupbeing on the sainelevel, the tracks of the central group being ar'-ranged some on thel saine level and sonie onl ranged in a centralsection and two iside' sections, the tracks lot said central sectionbeing on the saine level, one hall of the tracks of each side sectionbeing arranged onan upward incline and one hall ci' "the saine being ona downward incline, and the tracks ot the end Vgroup being arranged onthree levels one above another substantially 3. In a railway terminalstation, a` Vplurality of train tracks with suitable pla-t formsarranged on three different levels one above another, the trackson eachlevel ar# ranged'in tour groups with a single track` connecting witheach group, the our tracks connecting with the four groups on the middlelevel arranged substantially centrally of all the 'tracks of all threelevels, two tracks on either side of said our tracks leading to thetracks on the level below the iniddle level and two tracks on eitherside of said first named four tracks leading to the tracks onfthe` levelabove the middle level.

l. ln a railway terminal station, a plurality of. train tracks with.suitable platforms arranged on a plurality of levels, the tracks andthe platforms on the different levels being arranged in the sainevertical planes One above the other and suitableV switches and inclinedtracks connecting the saine vto the main line tracks leading into thestation so arrangedy that trainV from vany oi" the niain'line tracksiiiay be diverted in' its course to enter upon any desired track onani.r level in the station.

Having thus described and claimed niy invention, in testimony whereof lsign iiiy naine to this specification in Vpresence ot subscribingwitnesses at Chicago, Ill.
